Wideband beamforming based on Compressive Sensing

Wideband beamforming is of high significance in the field of array signal processing. However, most of the present methods would fail when some sensors of the receive array are not working and this situation occurs frequently in practical experiments. To address the problem, a new method of wideband beamforming based on Compressive Sensing(CS) is proposed. The received signal is first split into sub-band signals, then the full-array-signal is constructed on each subband and processed with beamforming technique. Finally signals are synthesized to get the wideband signal. Experimental result show the great performance of our proposed method and some additional examples are designed to further verify its effectiveness.
